Two opposing teams battle it out to regulate gene expression on the DNA playing field. One, the activators, keeps DNA open to enzymes that transcribe DNA into RNA. Their repressor opponents antagonize that ...

With the help of DESY's X-ray source DORIS III, an international team of scientists decoded an important weapon used by a widespread human herpes virus. The study reveals at the molecular level how the Epstein-Barr virus ...

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida have discovered a mechanism that explains how some cancer cells "hijack" a biological process to potentially activate cell growth and ...

(Phys.org) -- A team, led by scientists from the University of Dundee and the James Hutton Institute (JHI), have become the first researchers in the world to apply a new technique to sequence the genes of the plant Arabidopsis.

Lariats are discarded byproducts of RNA splicing, the process by which genetic instructions for making proteins are assembled. A new study has found hundreds more lariats than ever before, yielding new information about how ...

Enabling bioengineers to design new molecular machines for nanotechnology applications is one of the possible outcomes of a study by University of Montreal researchers that was published in Nature Structural an ...

Nitric oxide (NO) is a versatile free radical that plays central roles in the environment as well as living organisms. At low concentration in the human body, for example, NO protects organs against pathogens ...

A common point in all human tumors is that they produce an activation of oncogenes, genes that cause cancer and they also cause a loss of function of the protective genes, called anti-oncogenes or tumour suppressor genes. ...

Researchers have discovered critical new details about the structure of a virus that causes potentially fatal brain swelling and paralysis in children, pointing toward designs for antiviral drugs to treat ...

(PhysOrg.com) -- Cancer Research UK scientists have created the first 3D structure of a key protein that protects against the development of cancer, according to research published in Nature Structural & Molecular Biology today. ...

Scientists from The Scripps Research Institute and the US Army's Medical Research Institute of Infectious Diseases have isolated and analyzed an antibody that neutralizes Sudan virus, a major species of ebolavirus ...

A cell's genome maintains its integrity by organizing some of its regions into a super-compressed form of DNA called heterochromatin. In the comparatively simple organism fission yeast, a cellular phenomenon known as RNA ...
